In UK, the standard maximum input current limit for domestic usage is 100 amper. We should be safe using 60 A for mining.

Really?? My parents' house in Toronto has had 200 amps for, well, ages. I've heard, from an electrician friend, of posh houses being set up with 400 amps (!).

with what voltage? because 200 amp with 120v it's not different than 240v with 100 amp

In Canada, the residential mains voltage is 120V. So it is not different from UK 240V with 100 amp.

Yes, that's right - but as I indicated, the power folks will let you upgrade to 400 amps if you really really want to.

(Funny: my dad once told me that 200 amps used to be the smallest offering for light industrial...)

3. More GPUs; More Problems. - (Power draw, heat dissipation) Can the electrical wiring in your house handle 20 GPU's mining at once? Probably no.

One 20 amp 240v circuit run out of your breaker box can support 18 to 24 gpus without a problem.

For undervoltated R9 390, it will consume about 220W, or 1A for each card. So 20 amp is about 20 cards.

1A = 120W
220W = 1.833A

many house do not run that power, the standard power for normal people is around 3.3kw, with this you can at best put one 6-gpu-rig if you include the washing machine peak which is alone 1800w at least

Assuming you are running on a 240v circuit. USA 120 and you need to half this. MB & processor will eat up 100 to 200 watts.

hello guys, i want to ask about building a new rig i will spend like 2500-3000$ for it it will be with 6 gpus about 110 MH for ethereum my electricity per month its about 100$

My question is do you think i should do it because i heard the ether will move soon to POS mining and if that happend will i have a chance to mine some other coin and do you think i have a chance to make some profit?

Cloudmining is another opinion? I have allso plans to build mining rig on ETH. Some guys sell "plug and play" packages example eth mining

Just get rid of your washing machine and you're more than good to go. Wink

about the PC i have a friend who is gonna connect it so it can hadle 6 gpus because they already have 2 of those PC but my point is ....do you think i will make some profit even with altcoins ...because the ethere wont last forever i have and other idea to buy it connect it with ethereum and if it go down i will try other coins if it doesn work i will sell out the pc for about 60-80% of his price ...so it may works but i just want to see some other comments what the people here think about this...

I think it will take long to just break even on investment. Unless you get lucky with some coin.

i think to start it with 3 for now and later put more 3 ... but the point is do you think i will make a good profit witht this

1. Do not buy equipment on credit

2. Start small, scale up when you see it's working.

3. More GPUs; More Problems. - (Power draw, heat dissipation) Can the electrical wiring in your house handle 20 GPU's mining at once? Probably no.

4. It's impossible to say for sure how profitable (if at all) it will be.

Up to 6 GPU is easy to handle. After that you get start to get serious issues with heat and power most likely.

But getting 6 GPU's to work on 1 motherboard is POSSIBLE but damn hard. Not sure how it is today but this was the case about 2 years ago.
Your computer will most likely only detect 4 or 5 out of 6 cards and you will be scratching your head for a month how to fix it.

20 gpu should be okay for a house.
However, I would not go big unless you can afford to lose money if ethereum tanks down to 3 bucks again or even less.
This is a gamble.
However, a 4 gpu build is probably worth a go and if ethereum goes under then you can mine other alts in the future

The problem with starting small and getting bigger is that difficulty will grow during that time. My electricity is about half of what yours is (.08 kw). People in Washington pay as little as .025. People in Irkutsk pay .01 and don't have cooling issues.

It's all a gamble. And there are some folks out there with a huge competitive advantage.

i think you should start with two gpus and build it out accordingly.
